Equation are expressions equated to each other. The solution to the given equation is r = 3
Law of multipicity and reciprocal.
Equation are expressions equated to each other, Given the equation below;
1/4(r − 5/2) = 1/8
Expand
1/4r - 5/8 = 1/8
Add 5/8 to both sides of the equation
1/4 r = 1/8 + 5/8
1/4r = 6/8
Reciprocate both sides
4/r = 8/6
Cross multiply
8r = 24
r = 24/8
r = 3
Hence the solution to the given equation is r = 3
